PURPOSE:To vary optionally a pulse width and period without causing a time error by using a simple circuit. CONSTITUTION:This circuit is provided with a modulo counter 2 for setting a pulse width and with a modulo counter 3 for setting a pulse period, a flip-flop circuit 4 set/reset by the modulo counters 2, 3 and an OR circuit E2 receiving an output of the flip-flop circuit 4 and an input clock CK to the modulo counter 2. |
